Patent JP-H0269029-A (JP)
Title: Parallel optical fiber type transmission module
Inventor: OBARA YUICHI
IPC: H04B10/556
Filed: 1988-09-05
Abstract: PURPOSE:To make the fluctuation of the rising time of data signals at the receiving time allowable by providing a timing adjustment circuit which delays a control signal and adjusts the data reading timing by means of the signal on the receiving side of an optical fiber line for control signal. CONSTITUTION:An optical fiber line C for control signal is constituted to a hand shake line with a timing adjustment circuit 4. Because of the circuit 4, the light of a control signal emitted from a light emitting section 10 on a transmitting side is transmitted through an optical fiber 11 and converted into electric signals by means of a photodiode 12. The electric signals are amplified at the amplifier circuit 14 of a receivingside circuit 3 and converted into control signals after the electric signals are shaped in waveform by means of a comparator 15. The control signals are outputted, with the timing of the signals being delayed by one tempo. Therefore, even when the arrival time of data signals is more or less delayed, occurrence of a reading error which is a peculiar problem to a parallel type transmission line can be prevented, since the reading timing of the control signals is delayed by almost the same time as the delayed time of the data signals.
